Water surface wave is appeared in various scenes of computer games. In these usages, the shape of wave is necessary for human to acknowledge it real. The pictures are constructed by animation. Therefore the generation time of pictures is desirable to be short. For this purpose there are many cases in which the quasi・pictures are used. However it is better that the shape of wave in pictures approximates that of actual wave. In this paper for water in a rectangular parallelepiped, the analytical solution is constructed by Fourier series. This Fourier series is approximated by the DFT(Discrete Fourier Transform). In this paper the method of expression by DFT of the Fourier series is presented. In the case the point of DFT is selected as the power of 2, the FFT can be used to calculation. Several pictures of surface wave constructed by FFT are shown.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_10002_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.34411/00001046","subitem_identifier_reg_type":"JaLC"}]},"item_10002_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"神奈川工科大学"}]},"item_10002_source_id_11":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN10074179","subitem_source_identifier_type":"NCID"}]},"item_10002_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"09161902","subitem_source_identifier_type":"PISSN"}]},"item_10002_version_type_20":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"立花, 康夫","creatorNameLang":"ja"},{"creatorName":"Tachibana, Yasuo","creatorNameLang":"en"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2012-03-01"}],"displaytype":"detail","filename":"kkb-034-011.pdf","filesize":[{"value":"1.7 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"kkb-034-011.pdf","objectType":"fulltext","url":"https://kait.repo.nii.ac.jp/record/1053/files/kkb-034-011.pdf"},"version_id":"4b3e46ea-b7d9-4e4b-9a39-a742295a1adb"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"surface wave","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"fast Fourier transform","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"initial boundary problems","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"animation","subitem_subject_language":"en","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"FFT による水面波動の映像化","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"FFT による水面波動の映像化","subitem_title_language":"ja"},{"subitem_title":"Visualization of Water Surface Wave by FFT","subitem_title_language":"en"}]},"item_type_id":"10002","owner":"4","path":["124"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2020-11-24"},"publish_date":"2020-11-24","publish_status":"0","recid":"1053","relation_version_is_last":true,"title":["FFT による水面波動の映像化"],"weko_creator_id":"4","weko_shared_id":-1},"updated":"2025-06-23T02:50:11.744337+00:00"}
